German Patent No. 229,284.- dated 27th October, 1927 -discloses a particularly effective method of washing threads, especially artificial silk threads, wound 'on' perforated bobbins, which consists in causing air and/or gases and/or vapours together with a washing liquid to penetrate through the layers of wound threads.

The present invention has for its object to provide eil'ective apparatus Jfor carrying out of the method referredto. According to the invention, a rotatable frame is provided upon which the bobbins to be washed are arranged in such manner that on rotation of the frame the bobbins are periodically and intermittently `subjected to the action of the washing liquid, the interiors of the bobbins being connected to a suction pipe so that the washing liquid as well as the surrounding air and/or gases and/or vapours may be drawn through the layers of threads.

The suction pipe is conveniently connected with a central art of the frame,

such as a stuiliiig box, so that it may remain stationary whilst the frame rotates.

rlhe bobbins, which are constructed so as i to be permeable, may be arranged in any' suitable manner, for example, singly, upon the frame. They may, however, be suitably arranged in groups, by Stringing them in a manner known per se on rods or tubes with the interposition ofV packing rings. These groups are fixed ulpon the frame, suitable means being emp oyed for 'spacing the groups apart. Thus the groups may be arranged radiallyi. e. in the form of. a staror parallel to the axis-i. e. cylindrically-or in the form of a cone or in any 40-other suitable manner. In a particularly effective arrangement, groups of bobbins strung u on suitable tubular supporting rods or tu es are arranged so that the groups are disposed obliquely around the axis of the frame whereby the individual groups of bobbins constantly change their angular position with respect to horizontalk planesl This results in the practical advantage, that by choosing the correct direction and speed of rotation, the liquid drawn through the layers of threads may be caused to flow away laterally.

A simple constructional arrangement consists in rotatably mounting upon a horizontially in the form of a hyperboloid.

.the centre of one side with a connection to a vacuum p ipe, andon the other side with obliquely disposed connectionsA for groups of bobbins arranged, for example, substan- The liquid penetrating through the bobbinsl into the chamber can be drawn off by means of a Siphon or by means of scoo s or the like. -Op osite to the chamber a single support fort e outer ends of the groups of bobbins for example in the orin of a disc with notches or perforations can be arranged. In place of this a second similar chamber may be provided.A Y The movement of the frame, especially its rotation, may be uniform or intermittent, slo w or rapid, in any case such as is most suitable -for the periodic action of the washing liquid.

The washing liquid may be placed in a trough underneath the frame, the bobbins dipping into the liquid once at every revolution. The periodic moistening of the bobbins, can, however, be effected in other ways, for example by irrigating or by spraying.

A suitable construction of apparatus is illustrated, by way of example, in the accom p anying drawing in which Fig. 1 is a sectional elevation and Fi 2 is a cross-*Section near the vacuum cham er. Fig. 3 is a section through the suction or vacuum'chamber.

The vacuum chamber is mounted on the shaft a, which is carried in the supports and is rotated by the belt drive o. In the centre of the chamber there is an opening for the suction pipe f packed by the stuling box e. This suction pipe 'f is bent downwards in the interior of the chamber "d, so that it siphons oil' the washing liquid lowing into the chamber. On the outside of the chamber obliquely disposed support connections g are provided, on which the groups of bobbins h, .arestrung, said bobbins being arranged end to end with the interposition of packings z'. At their other end the groups of bobbins are supported in a disc lo provided with suitable recesses, while, if necessary, the groups can be pressed suitable means (not shown). The whole ame rotates over the trough Z7 containing the washing'liquid., Owing to the oblique positions of the ou s of bobbins as they leave the troug t e washing liquid is enabled to flow of into ilo suction, and means the chamber d. As shown in Fig. 3, the suction tube f has a liquid-tight ackng e. Likewise, the supports g are tubu ar.

I claim Y 1. A paratus for washing threads wound on bob ins, comprising a rotatable chamber, means connecting the said chamber to a source of suction, tubular fittings upon which the bobbins with the interposition of packing, are strung end to end in grou s, the said ittin s 'communicating with t e interior of t e' bobbins and with the interior of the said chamber and -means by which the bobbins may be periodically and intermittently subjected to the action of a washing liquid and a gaseous medium such as air.

2. Apparatus for washing threads wound on bobbins, comprising a rotatable chamber upon which the bobbins are carried, tubular fittings extending from the said chamber fupon which fittings the bobbins with the interposition of packing are strung end to end in groups2 the said fittings communicating with the interior of the said chamber and with the interior of the bobbins and .being arranged so that during the rotation of the said chamber the washing liquid enterin the said bobbins flows off laterally, an

means connecting the said chamber with a source of suction. Y A i 3. Apparatus for washing threads wound on bobbins comprising a rotatable element, tubular fittings carried by the said element and upon which the bobbins with the interposition of packing are strung end to end in groups, the said fittings being arranged obliquely around the axis of the said element so that their inclination with respect to horizontal planes changes constantly during the rotation of the said element, means connecting 'the said fittings with a vsource of by which the bobbins may be periodically and intermittently subjected to the action of a washing liquid and a gaseous medium suchas air.
